Has anyone out there experienced difficulty raising and lowering their main form the cockpit using these deck organisrs? On my 29.5 I have the three-sheave organisers (one of each) on both the Port and s/b side of the cabin roof. The main halyard is 1/2" and I can get the main up around 60% of the way from the cockpit, but then I have to go to the mast to do the rest. The sheaves are free, and because I can raise the main from the mast, I wonder if it is just an allignment issue form there, through the tunel to the clutch.Anyone encountered this or needed to do any modifications?ThaksNeil
